Description

Cap-rotating type fidelity bottle cap

The utility model relates to a kind of false proof, cap-rotating type fidelity bottle cap that fidelity is used.

Available in the market anti-false true-guaranteeing bottle cap is of a great variety, structure is different, but what the weakness ring of most bottle caps adopted is push-press type bending failure technology, weak ring is closing form, and is provided with singlely, and the destruction of weak ring is directly finishes with the hand application of force, time-consuming, effort, and be difficult to guarantee safety, adjustable is also relatively poor.For example: the anti-fake bottle lid of patent ZL9521154.5 is exactly like this.

The purpose of this utility model is exactly to design a kind of cap-rotating type fidelity bottle cap that utilizes fashion of extrusion fail in shear technology as the weakness ring, this weak interannular is connect with the hand application of force or reinforcement to be destroyed, both laborsaving during destruction, safe and reliable again, as not lose anti-false true-guaranteeing simultaneously effect.

The utility model is by upper and lower cover structure, core plug structure, the bottleneck structure three parts constitute, it is characterized in that: bottleneck structure is to be made of a bottleneck cylinder, bottleneck cylindrical center upper end is a round bottle oral pore, around in the bottleneck hole be one greater than cylindrical round platform, round platform has constituted bottleneck end face and bottleneck retaining ditch, below the retaining ditch, the outside of bottleneck cylinder four retaining strips that distributing equably, bottleneck cylinder lower end is enclosed within on the bottleneck.

The core plug structure is by a core plug, and one group of patch that core is overlapping beyond the Great Wall constitutes, and core plug top is a core plug edge greater than the core plug, handle and core plug along above be connected, establish a handle aperture on the handle, the core plug is inserted in the bottleneck hole together with patch, contacts with the bottleneck end face along following to the core plug.

Following tops has a lower cover apical pore, there are four well-distributed retreat stop blocks lower cover inwall upper end, lower cover is enclosed within on the bottleneck cylinder, make the lower cover apical pore be inserted in core plug handle, along top applying, four retreat stop blocks on the lower cover inwall are against in the bottleneck retaining ditch lower cover inner face tightly with the core plug, and retreat stop block and bottleneck retaining strip are in sustained height, staggered installation, lower cover inwall and bottleneck cylinder bearing fit.

Four retreat stop blocks that cover down are both narrow thin weakness rings.

Loam cake is enclosed within on the corresponding face of cylinder of lower cover by the knock hole bearing fit on it, and a positioning table is arranged on it, by the semicircle scrobicular ring that covers down and on the semicircle bulge loop that covers constitute lock ring.

Perhaps do not establish retaining strip on the bottleneck cylinder, and establish a biconvex helical surface in the bottom of bottleneck cylinder, correspondingly establish a concave-concave helical surface in the lower cover bottom, during assembling, helical surface is fitted fully.

The utility model design-calculated cap-rotating type fidelity Bottle cap structure is simple, the design resultant, weak ring adopts two kinds of different stress destruction forms, a kind of is that the circumferencial direction extrusion shearing destroys, a kind of for the vertical direction extrusion shearing destroys, the destruction of weak ring is finished with the hand application of force indirectly, has safe and reliable, save time advantage such as laborsaving.

Cap-rotating type fidelity bottle cap described in the utility model is made up of three parts: bottleneck structure, upper and lower cover structure, core plug structure.

Bottleneck structure is to be made of a bottleneck cylinder (18), bottleneck cylindrical center upper end is a round bottle oral pore (17), around in the bottleneck hole be one greater than cylindrical round platform, round platform has constituted bottleneck end face (16) and bottleneck retaining ditch (15), below the retaining ditch, the outside of bottleneck cylinder four retaining strips (20) that distributing equably, bottleneck cylinder lower end is enclosed within on the bottle.

The core plug structure is to be made of one group of patch (2) that a core plug (1) core is overlapping beyond the Great Wall, core plug top is a core plug edge (4) greater than the core plug, handle (7) is connected along top (5) with the core plug, for anti-skidding, establish a handle aperture (6) on the handle, the core plug is inserted in the bottleneck hole together with patch, and the two is a transition fit, very ends with the contact of bottleneck end face to the core plug along following (3).

A lower cover apical pore (13) is arranged at lower cover (22) top, and there are four well-distributed retreat stop blocks (14) lower cover inwall upper end.The heating lower cover is enclosed within it on bottleneck cylinder to certain temperature, makes the lower cover apical pore be inserted in core plug handle, and is pressed on the bottle (19), fits along top (5) with the core plug to lower cover inner face (12) and ends.At this moment, lower cover inner face (12) is fitted along top (5) with the core plug and is ended.At this moment, the retreat stop block on the lower cover inwall (21) is because the effect of bottleneck cambered surface,, and tightly is against in the bottleneck retaining ditch for being inclined upwardly from downward-sloping upset.Retreat stop block and bottleneck retaining strip are in sustained height, the staggered installation.Because the mutual barrier effect of retreat stop block and retaining strip, the lower cover inwall can not rotate and can not withdraw from relative to bottle.Lower cover inwall and bottleneck cylinder bearing fit.So far lower cover, bottle, core plug have been finished mutual location, connect, and install.

Lower cover is by four retreat stop blocks and bottle location mutually, and retreat stop block is not only thin but also narrow to have formed a weak ring, and before it did not destroy, the core plug can't be extracted from the bottleneck hole, promptly can not uncork.

Loam cake (11) is enclosed within on the corresponding face of cylinder of lower cover by the knock hole on it (9) bearing fit and locatees, with the positioning table on it (10) stop.And with lock ring (8) with the two pinning, suitably exert oneself just to close or open, like this good airproof performance.Lock ring be by the semicircle scrobicular ring that covers down and on semicircle bulge loop two parts of covering constitute.

Another kind of scheme is not establish retaining strip on the bottleneck cylinder, and does a biconvex helical surface in the bottom of bottleneck cylinder, correspondingly does a concave-concave helical surface (24) in the lower cover bottom, and during assembling, two helical surfaces are fitted fully.This is a force-increasing mechanism, when making the circumference tangential force be transformed into vertical forces, but the reinforcement several times.

For anti-skidding, increase friction, outside lower cover, be carved with straight burr groove (23).

When needs were opened bottle cap, left hand was held bottle, and the right hand is pulled up loam cake, holds lower cover straight burr groove section then, and clockwise direction rotates lower cover, because of under the retreat stop block that covers and the retaining strip on the bottleneck stop mutually, and can not rotate.So slightly once weak ring firmly by disconnected along circumferential shearing and destroy, upwards take down lower cover, can extract the core plug, then bottle is opened.

For II type bottle stopper, because of the helical surface effect, the vertical direction that also will make progress when lower cover rotates in the clockwise direction moves and reinforcement.And retreat stop block is tight against on bottleneck retaining ditch, and it can not be moved, thus one exert oneself slightly, and under the force-increasing mechanism effect, weak ring is just vertically sheared disconnected and is destroyed.
